BRICK-KILN.

SPECIFICATION forming part of Letters Patent No. 385,209, dated June 26, 1888.

Application filed August 19, 1887. Serial No. 5247.394. (No model.)

To @ZZ whom, it may concern:

Be it known that I, GEORGE W. SHARER, a citizen of the United States, residing at Terre Haute, in the county of Vigo and State of Indiana, have invented certain new and useful Improvements in Bricl;-Kil1is; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it ap pertains to make and use the same.

In working brick-kilns it is essential that the products of combustion passing through the different eyes be under complete control, as it often becomes necessary to check the draft in one or more of the eyes and to cause the products of combustion te pass through the other eye or eyes, as the case may be, to give increased heat in that part or parts ofthe kiln to which the eyeor eyes lead. Various ways of introducing cold air into the eyes have been used; but none of them are effective for the reason that the air has never been introduced at the p oint of greatest heat-i. e., the upper part ofthe eyes.

The object of my invention is to overcome these defects; and to that end the nature of theinvention consists ofconstructions and eembinations, all as vwill hereinafter be described in the specification, and pointed out in the claims, reference being had tothe accompanying drawings, in which* Figure 1 represents a perspective of my kiln with parts of the furnace broken away to show the air-fines; Fig. 2, a front elevation with parts broken away to show the air-fines; Fig. 3, a transverse section through one of the furnaces; Fig. 4:, a horizontal section vof several furnaces taken on different lilies; Fig. 5, a transverse section of the furnace adapted to use oil; and Fig. 6, a sectiononline 6 6, Fig. 5.

Areprcsents the kiln, having eyes a u a2, arranged in sets, each of which opens into the combustion-chamber A of the furnaces A2, which are provided with the usual appurtenances. Each furnace has two peep holes, a3 a, which respectively lead into the combusf tion-chamber at a point opposite the eyes a and a2. Near the rear end, at each side of the furnace, are formed the ai r-passa ges e a, which begin near the bottom and terminate just back of the grate and on aline with the skcwback.

In that part of the wall between the furnaces passages a7 a8 ai are formed. Passage a7 leads inwardly to a point opposite to the eye a, and

is then deflected upwardly to a point above the eye e, and then brought down through the npper wall of the eye. Passage as is brought in through the wall between the first and second furnace and deflected inwardly and over to and into the top ot' eye a2. Passage a is located below passages el and a8, and passesinto the wall on a horizontal line between passages e7 and as, and is defected at right angles under eye Sinto the abutment B, and then.` upwardly alongside of eye a, and then into the upper wall of the said eye.

It will be seen from the foregoing description and the drawings that the air is admitted into each eye at the top-the point of greatest heat in said eyes-and the draft is thus effectually checked. To prevent the air from passing through when not desired, caps al, having a pivotal attachment on the wall, are placed over each opening, and when desired can be removed from the mouth of the openings, so that the air can pass in to check the draft.

It may often be desirable to construct the furnace to burn petroleum or other hydrocarbons, and the form of rebox and abutments shown in the drawings are particularlyadapted therefor. It will be noted that the fire boxes on the right-hand side of the device shown in Figs. l, 2, andi are particularly designed for this purpose. This construction is shown more fully in detail in Figs. 5 and 6.

Instead of a grate, a pan, b, to receive oil and water from any suitable source and fed by the supply-pipe shown, is placed in the firebox. Air necessary for combustion may be admitted around the pan; but l prefer to form a vertical passage, b, and a horizontal passage, b2, which is connected by a second vertical passage, b, with a chamber, b, having subdivisious formed by bricks placed crosswise, and

opening into the fire-box in the side walls of the furnace to supply the air necessary for combustion.

To get the best result from this fuel, the abutments B B are formed with facets b, which are immediately in front of the fire-box, and facets b?, which extend obliquely and rearwardly from the facets b and serve to form ICO the fines leading to the side eyes. The object "of the facets b is to compel the products of -termingling of the gaseous fuel from the burner and the air admitted through the side walls of the furnace.

In the front wall of the kiln are placed two rods, B3 B4, from which rods be project out- 'Wardly through the uprights Bi', which are secured in place by the nuts b.

I am aware that hot air has been introduced into the.combustion-chamber for the purpose of increasing the combustion, and make no claim thereto, as'my device differs from that class of devices in that the object sought to be accomplished is entirely different, to wit: to check the draft which is accomplished by introducing cold air into the eyes, in the manner heretofore described.

'What I claim as 'new is-n 1. In a brick-kiln, the combination of a furnace, the Wall of the kiln having eyes connecting the furnace with the interior of the kiln, and eold-air passages in the wall of the kiln and opening into said eyes through the top wall of the latter, substantially as described.

2. In a brick-kiln, the combination of a furnace, the wall vof the kiln having eyes connecting the furnace with-the interior of the kiln, and the cold-air passages, oneleading t0 each eye, and the one leading to the middle eye 'passing under one of the other eyes, substantiall y as described. v

3. In a brick-kiln, the combination of a furnace, the wall of the kiln having eyes connecting the furnace and the interior of the kiln, and cold-air passages leading from the open air into the eyes, and the passage to the 4c middle eycpassing around one of the side eyes, substantially as described.

4. In a brick-kiln, the combination of a furnace having passages b b2 b3 and chamber b4,

subdivided by bricks, and the front Wall of 45 the furnace having abutments provided with eyes and facets b and b7 and abutting in the combustion-chamber of the furnace.

In testimony whereof I affix my signature in presence of two Witnesses.
